Normally, you can use the JDK (Java Development Kit) with an IDE (Integrated Development Environment) to develop.

To start testing Java, you can type jshell in your command prompt and code a little bit.

Alternatively, the easiest way to start is by creating a simple Java class (using Notepad, for example):

public class Main {
public static void main(String[] args) {
System.out.println("Hello world!!!");
}
}

Save the file as Main.java. Open the file directory in your command prompt and type:

javac Main.java

And finally type,
java Main

You'll have "Hello world!!!" as result. I hope that helps!
